IAMG selects and sponsors two lecturers each year: The IAMG Distinguished Lecturer and the George Matheron Lecturer.

The Distinguished Lecturer prepares a series of lectures preferably on a variety of subjects in the mathematical geosciences to be presented in places where IAMG Annual Meetings are not normally held.

The Georges Matheron Lecturer should be a scientist with proven research ability in the field of spatial statistics or mathematical morphology. This lecture is presented at the Annual Meeting of the IAMG.

The Council appoints two committees to seek nominations and select a lecturer for each of these series.
